For Gurobi Remote Services, there are two types of license files: server and client. A server license file is much larger because it contains the information to run the remote services. The client license files contain just enough information to point Gurobi to the server. Below, we have an example of each for Gurobi Compute Server and our Token Server.
Compute Server license files
Example client license file
Here is an example of a client license file that would allow a client to connect to a Cluster Manager with an API key and submit all the jobs under a specific application name:
CSMANAGER=http://mymanager:61080 CSAPIACCESSID=0e8c35d5-ff20-4e5d-a639-10105e56b264 CSAPISECRET=d588f010-ad47-4310-933e-1902057661c9 CSAPPNAME=app1
Here is another example that would allow your client to connect a self-managed Compute Server with a specific password, and submit all the jobs with priority 10:
COMPUTESERVER=http://server1:61000 PASSWORD=abcd PRIORITY=10
